How to Change the Coolant in a 2024 Beta XTRAINER

Shop parts for a 2024 Beta XTRAINER Dirt Bike.

Routine maintenance, like changing your coolant, is essential for keeping your 2024 Beta XTRAINER running at peak performance. The XTRAINER's compact, high-revving two-stroke engine and smaller radiators make proper coolant management especially important for preventing overheating–something riders often encounter in slow, technical terrain.

Why Coolant Matters on the XTRAINER

Beta designed the 2024 XTRAINER for agility and ease of use, but its smaller radiator volume means the thermo fan works hard during slow, technical rides to maintain optimal engine temperature. Upgrading to a high-volume coolant pump is a common mod for riders tackling tough singletrack, as it pushes more coolant through the system and keeps temperatures under control. Keeping the coolant fresh and at the right level maximizes the engine's service life and performance.

Tools and Supplies Needed

  • Fresh coolant formulated for dirt bikes
  • Socket wrench set
  • Drain pan
  • Flathead screwdriver
  • Protective gloves
  • Funnels and clean rags

Step-by-Step Coolant Change Guide

  1. Cool Down & Prepare: Make sure the engine is completely cool. Secure the bike upright on a stand or level surface.
  2. Remove Radiator Cap: Unscrew the radiator cap on the left-side radiator. This relieves system pressure and allows air to enter as the coolant drains.
  3. Locate and Remove the Drain Bolt: Place a drain pan underneath the engine. The drain bolt is typically found near the water pump cover at the bottom of the engine case. Using a socket wrench, loosen and remove the bolt to let the old coolant flow out completely.
  4. Flush (Optional but Recommended): For a more thorough service, gently flush the system with clean, distilled water before replacing the drain bolt.
  5. Replace the Drain Bolt: Once the system is empty (or flushed), reinstall the drain bolt and tighten it to the manufacturer's spec.
  6. Fill with Fresh Coolant: Pour your new coolant slowly into the radiator opening. On the 2024 XTRAINER, the coolant level should be just above the tops of the radiator fins inside the cap neck–never fill above the neck.
  7. Bleed Air from the System: The XTRAINER features a dedicated bleeder screw on the left radiator—a feature not found on all Beta models. Loosen this screw briefly to allow trapped air to escape until coolant flows out without bubbles, then retighten securely.
  8. Reinstall Radiator Cap: Double-check that everything is tight and reinstall the radiator cap.
  9. Start and Check for Leaks: Start the engine and let it idle until it warms up. Shut it off, let it cool, then recheck the coolant level and inspect for leaks. Top off as necessary.

Key XTRAINER-specific Tips

  • The XTRAINER's radiator system is compact, so pay extra attention to proper bleeding. Air bubbles can cause rapid overheating.
  • Keep an eye on the bike's temp in slow or technical rides–the thermo fan cycles often due to reduced radiator size.
  • If you consistently ride extreme terrain or experience overheating, consider upgrading to the high-volume coolant pump kit to improve circulation and cooling.

When to Replace Coolant

As part of preventative maintenance, change the coolant at least once a year or every 20–30 hours of use, whichever comes first. Inspect before long rides, especially after heavy or technical use.

Final Checks

  • Ensure all caps and bolts are securely fastened.
  • Dispose of old coolant safely–never pour it down a drain or on the ground.
  • If you're changing coolant for the first time, consult your Beta owner's manual for specifications and tightening torque values.
